The Budapest Ubuntu Developer Summit (UDS-O) kicked off on Monday, May 9, at the Corinthia Hotel. "Accessibility is one of our core values as a project," Canonical founder Mark Shuttleworth said in his keynote address, as he acknowledged the Unity documentation team contributions to the 11.04 release. After briefly looking back at the "Natty Narwhal" Ubuntu release, Shuttleworth set his sights on the upcoming release, saying, "Our goal, our mission is 200-million Ubuntu users in four years."
